The offer of this type of banana plugs is quite large here. The function and quality is expected to hardly differ in this price range. The Hi-end philosophy and its followers, I know it from my own experience, of course, offers the possible to the discussion of sound, etc. For me, they are the link between a NAD amplifier and the transformer to Jacklin float and satisfy very well its purpose.

The thread for the sleeve and the cable attachment do not run clean and edges. The cable storage is equivalent to specifying. To 6.0 mm² to be well received and secured by two screws. It may be that you have to solve one or the other screw and re-tighten, otherwise the sleeve can not be fixed.
